Pieced together a tune

OK this is what I got on the truck right now.
2000 GMC Sierra Extended cab

Long Tube headers
No cats
No EGR
8.1l inj
CAI
LS1 Fans
Corvette servo
100 Shot wet NOS

First I did not use NOS on the run in the log. Im not going to use it untill I get positive feedback from yall. I pieced together a tune from the repository. Im just getting started and would like to know what I can improve on. I took the truck around the block and really like the added power, but just wanted to make sure everything looks good, im a newb so im just being cautious.

Your injectors flow rate table in not scaled correctly for the 8.1 injectors,if they were marines it would be alittle closer but not the 8.1's
you pe table is jacked.Get a wideband,dial in your VE and MAF and work on that timing table
I would not spray any nitrous with that tune,you will run into problems
Your LTrims are 20+ which is not good either
There is alot left on the table in that file!!

Do I need the PRO version to run WB?
Ill set it back to stock other than the injectors.

just work with it and log it
You really need a wideband to get your MAF and and VE table dialed in

You can run a WB through AC pressure or EGR and 'cheat' that way. There's some good threads on it on here.

Also, you could trim tune your MAF and VE- it will get you much closer until you get the WB hooked up. I recommend skipping LTFTs and just tuning via STFT's if you go that route- it's much quicker.
